METER INSERT FOR HEATERS.

Application filed August 12, 1920. Serial No. 402,988.

My invention relates to a weir section, capable of being built into an open feed water heater construction without disturbing the water storage portion of the bottom of the heater.

The purpose of my invention is to provide an intermediate section, containing a weir meter, and capable of insertion in existing heaters, supplying a meter compartment therefor, and using the bottom of the heater for a catch basin or capable of-being built into a heater in a new construction.

A further purpose is to provide a weir meter section, capable of interlitting with steel plate heater construction.

A further purpose is to provide a weir meter section, whose upper part is adapted to act as the bottom 01 an open feed water heater, providing valved inlet between the feed water heater bottom water storage space and the meter above the weir.

A further purpose is to form an entire meter section with water storage for the heater and valve for water control, capable of interconnection with the upper or upper and lower sections of a 'feed water heater.

Further purposes will appear in the specification and in the claims.

I have preferred to illustrate my invention by but one general construction, among the various vterms which it may take, showing a type which is practical, eflicient and flexible, easily constructed and readily intenhangeable for dillerent feed water heater constructions, and which at the same time well illustrates the principles of my invention.

In the drawing, Figure 1 shows a vertical, longitudinal section, partly in side elevation 01" this preferred form of my invention.

Figure 2 is a transverse sect-ion taken above the weir and partly in top plan, showing this preferred form.

Figure 3 is a transverse section, similar to Figure 2, but showing a modified form of weir chamber.

Figure 4 is a section taken on the line l4l-. of Fig. 2.

In the drawing similar numerals indicate like parts.

Many existing open feed water heaters cannot utilize weir meters because of the limited floor area available. If a weir meter can be interposed between existing parts of this heater or beneath it, using a portion of the heater structure, there is the double benefit of conserving floor space and saving in reduced installation cost and in time of installation. Even where the existmg parts of the feed water heater cannot be used, a new heater and meter can be built upon the same floor space as had been used for the heater above.

For new installations, even where ample space is available, or where the location of other apparatus makes the installation of a weir meter between the heater and the feed pump diflicult or undesirable, it is quite advantageous to be able to include a full meter construction upon the ground space required by the heater alone, and without losing any of the advantage of separate and distinct weir meter construction.

1 have sought to provide an equipment of this character with distinct and separate inlets, capable of control by the overflow of water in the catch basin, and which can be connected to the upper portion of an existing feed water heater of some of the types already on the market, so that its upper section containing the inlet valve will form the bottom of the feed water heater and hold part of the storage water of the heater.

By way of illustration and not by way of limitation, I will now describe my preferred form.

The feed water heater 4 is provided with the usual return steam connection 5 valved at 6 and with a make-up water connection 7, controlled by float 8, lever 9, rod 10, lever 11 and valve 12. There is also an overilow control for water from the heater by means oi a pipe 13, valve l-fl, a float 15, rock shalt 1G and operating rod 17, permitting water to flow out of pipe 13 when the valve is open.

The upper half of the heater is shown as joined to a meter section 18 and for that purpose terminating in flanges 18 which may be below or above the intended lower level of storage water in the heater, but are here shown as below that level to provide for part of the storage within the section of heater above said flanges 18.

The meter section 18, which here forms an insert between old heater parts, is shown as flanged at 18 to cooperate with the flanges 18, and contains the combined floor and cover wall 19 providing a compartment 20 in the upper part thereof, which may form part which water or rulllc the level oi? water in the meter. The dili'crcnrc bclwvecn the sections shown in Fig. 2 end his. 3 lie chiel'ly in the fact that the inlet end weir in liig 2 are termed at 353 and Qt: respectirely, er diagonal co ners of the construction. ,e encrally as sl in patent to la Chane, llo. 1,5.)81577 diagonal flow meters, wl crcus in weir inlet (beneath the heater entice i at any suitable point along; the side 2'7, p eferably near the corner, and the weir e at 26' is located at a point, 7 "iatciy in the middle of one oi? the sides and not in or near a corner as in the construction of Fl nn-es 1 and 2.

The lower part of the we r section is flanged at 28 to c operate with flanges 5353 upon a lower section 29 wh'ch. is intendc l to act as a storage basin and i r wlllCll the outlet water flows to the pump llllffillffll pipe 30.

Both the inlet water above the weir and the outlet througl'i this pipe 31 can be controlled from a float or floats in the catch basin if desired, as these control conncctioinii are old in themselves. I have not explained them in any great detail herein but would refer to U. S. patent to Yarnall, No. 1.064.806. issued June 17, 1913, for any further inlornnition desired. In the illustration ot his present application a control floa t Ill operates through rocker arm 32 and.

connections 33.. 34-, 05 to open and close valve 22 or keep it open to varying extents in inverse proportion. to the height oi water in the storage space.

The meter section is connect-ed a) ll recording float 37. and carr' case 38 and suitable recording niccl by which the rate of flow may be sh in existing weir meter types.

A weir plate is shown at 39. At any convenient point sight openings are provided at 4-0 and valve controlled, pr r-izsnre interchan connection between the weir chamber and the heater is provided by pipe l1.

The overflow of water from the weir passes down through an opening 4i? into the catch basin, which is shown as of the extra storage type, i. e., permitting storage of water directly Jencath the weir chamber. This basin is formed by the lower hall of will enter the nictir space i3 5 the standard feed water heater with its full filtering area and water storage-capacity re- 1 nnng nndinnnished. In the case ot an, ex sting heater this bottom section need not be moved and its connections rcniain undistin-bed.

My inctcr insert offers COllSlClCliLblQ advantage, both in new and old installations. In the design of new heater-meter units, the manufacturer of rectangular leaters need not alter his heater patterns but can make the heater of square plates on the four sides as in the Swarthout heater, for 02'- :nnple, and can insert the meter section between the standard upper and lower heater sections.

in the :ase oi ex ,7 'ng heater installation, the lower heat 1' section originally used for dlli'Ol sl'o 'age for the pumps rcn'iains undisturbed, but becomes the catch basin; the "ter left in place, and the float originally used for opemting the make-up water valve is ised for control of the inlet of the weir chamber. The upper heater section is raised and the meter insert is placed ictwcon the two heater sections. The placing of the desired floats or the changes in their connections involve little difliculty.

The heater is provided with a storage space wholly or largely provided by the compertinent forming the upper part of the meter insert. However, this need not hold nearly the quantity of water desired as storfor the pump but only sullicient to smooth out or equalize the flow to the meter.

In View of my disclosure herein a, variety of ways will occur to others srilled in the art by which advantage of my invention may be taken, suiting to the preference or whim of the designer. I aim to protect all of these forms which come yithin the spirit and scope of the invention.

Having;' thus described my invention. what I claim as new and desire to secure by Letters Patent is A weir meter insert comprising a weir plate, a storage section above and in communication with the weir plate of which the plate forms it sort, a space below the weir for fall of liquid to a catch-basin, a catch basin, a partition over the weir storage section and space and an opent-op water storage section having the partition for its floor and adapted to be connected as the bottom of an open teed water heater.
